RESILIENT HEEL LIFT.

Application med November 26, 1917. Serial No. 203,987.

To all whom t may concern.' i

Be it known that I, RAYMOND L HILL, a citizen of the United States,reslding at Elyria, in the county ofLorain and Statel of Ohio, haveinvented certain new and 'useful Improvements in Resilient Heel Llfts;

' and I do hereby declare the following to be tached to a shoe heel.

a full, clear, and exact description ofthe invention, such as' willenable others skilled in the art to which it appertains to make and usethe same.

The object of my invention is to provide a resilient heel lift whichwhen attached to a shoe heel will automaticall closed, especially at theedges, t e seam betweenthe attaching faces of the rubber and leathersections of the shoe heel, thus avoiding the use of cement or otherauxiliary attaching medium.

I' also aim to w,produce a device of the character described, which inaddition to accomplishing the above-named objects, is simple andconvenient to make and to attach to the shoe heel.

lThese and other objects of my invention and the invention itself willbe understood from a description of an embodiment of the invention.

Fig. 1 is a plan view of an embodiment of my invention showing theattaching face thereof. Fig. 2 is a section taken thru the line 2--2 ofFig. 1. Fig. 3 is a section taken thru the line 3--3 of Fig..1. Fig. 4is a view of a heel lift embodyin my invention, at-

ig. 5 is a transverse section of a second embodiment of lrny invention.Fig. 6 is aplan view of the attaching face of another embodiment of myinvention. Fig. 7 is a vertical section thru the line. v'i1-,7 of Fig.6. Fig. 8. is a vertical sectioiij'thru the line 8'-8 of Fig. 6. Fig. 9is' a sectional view of the lift attached to a leather shoe heel.

Referring now to the drawing and to the embodiments shown therein, at 5is shown a heel lift made of some resilient and elastic material andhaving the general outline of a shoe heel. The tread face ofthe lift isshown at 6 and the attaching face, at 7. ln the embodiment shown thesefaces are substantially parallel to each other, though itl maintain lugprojecting from the central portion of Maaate the attaching face of theheel and in the embodiment shown, having a surface shaped like thesegment of an ellipsoid.

A depression or crater 9,is formed in the tread surface of the heel,Which should be opposite and preferably of substantially the sameoutline as the protuberance 8 and opposite thereto, so that when thelift is attached to a shoe, both the protuberance and the crater will beretired, leaving a substantially flat lift, n Openings are shown at 10for the attaching means, such as screws or nails. Washers 11 should beplaced about these openings for the heads of the nails or screws. Theopenings 10 and washers 11 are placed between the apex 12 of theprotuberance and the marginal edge 13 of the lift.

When the lift is attached to a shoe heel, the nails or screws appliedthru the openings 10 will draw the lift close against the heel of theshoe, depressing and partly compressing the protuberance 8 andstraightening out the faces of the lift so that the protuberance will besprung in towards the body of the lift, and both `the protuberance 8 andthe -of the point 12, to rotate the different sectors of the heel aboutthe attaching devices as pivots, and thereby force the marginalportions'of the heel lift against the corresponding parts of the leatherheel of the shoe. 'This effect will cause the portion 16 of theattaching face to hug very close to the corresponding leather portionsof the heel to which the lift is attached. 4 As a result, the seam willnot only be closed at the edge, but throughout the inter-engaginattaching surface of the leather and ru ber sections of the heel. Thecentral portions will be maintained in close contact by the effort ofthe protuberanoe 8 to return to normal, the intermediateA portions bythe nails or screws andthe marginal portions by the eort of theprotuberance to rotate the sectors of the lift about the attaching meansas a pivot. l

In Fig. 5 the protuberance is shown at 8'-, but there is nocorresponding crater in the fil tread tace. l'Ihe protuberance is soproportioned that any deflection caused 1n the tread .surface when vthelift is attached to a shoe comprisesv a net work of vertical members:'10, which are composed of yielding material. As these webs are maderelatively thin, they yield individually and collectively. As shown inFig. 9, when the lift is mounted on a shoe, the members 50 arecompressed, and in tending to regain their normal position, they exert aforce upward in the direction ot the arrow p, which, acting thru thepoints o o as a pivot, tends always to rotate `the margins 131, 131downwardly in the direction of the arrows g Vq, thereby causing the heellift to cling closely to the leather, especially at the margins. 'Iheforce with which I the margins cling to the leather may, of

course, be varied by changing the heights of the protuberance 108, orvarying the number and size of the webs constituting the same.

It will be appreciated that the protuberance, (and where a, crater isused, the crater) may be of any suitable shape and that the atl tachingmeans may be placed at any suitable position, though it will be apparentthat they are best placed in such a positionas to realize the greatesthugging effect at the edges of the lift.

I have shown these embodiments of my invention and the details thereoffor the purpose of better describing the invention.` It will be apparentthat numerous and extensive departures may be made from such embodimentsand details without departing from the spirit of the invention.

I claim 1. A resilient heel lift having a fiat marginal portion, andinside the marginal portion having on the attaching face a protuberance,and on the tread face a crater of substantially the same outline as theprotuberance, said heel lift having means outside said protuberance forreceiving attaching devices.

assegno 2. A resilient heel lift having a dat man ginal portion, andinside the marginal pory r a protuberance, the thickness of the bodyportion of the heel being substantially as great at the protuberance asbetween the protuberance and the margin, -and said heel having betweenthe protuberance and the outer edge of the heel means for receivingattaching devices.

4;. A resilient heel lift having on the attaching face a protuberanceand on Ythe tread face a crater of substantially the same out# line astheprotuberance, and a flat marginal surface surrounding the crater,said heel litt having means between the crater and margin for receivingattaching devices.

5. A resilient heel lift having on the attaching face a protuberancewith a flat marginal surface surrounding it and on the tread face acrater of substantially the same outlineas the protuberance, said heellift having means between the protuberance and margin for receivingattaching devices.

6. A heel for shoes comprising a body portion having a substantiallyflat marginal port-ion of equal thickness throughout, and having a bulgeon the attaching side of the body portion and a corresponding depressionon the wearing side thereof by which thematerial at the bulge issubstantially equal in thickness at the bulge to the thickness of thebody portion.

7 A heel for shoes comprising a body portion having assubstantially Hatmarginal portion of equal thickness throughout, and having a bulge onthe attaching side of the body portion at the middle part of the bodyportion with a corresponding depression on the wearing side thereofwhereby the material at the bulge is substantially equal in thickness atthe bulge to the thickness of the body portion and adapted to beflattened out 1n application to a shoe whereby the tread surface will besubstantially dat.

In witness whereof, I have hereunto signed my nam@J this 19 day ofNovember, 1917.

RAYMUND I. HILL.
